Description	V tomto príspevku sa zameriame na oxidáciu primárnych sulfitických minerálov ako hlavný dôvod pre kryštalizáciu tripuhyitu v prostredí banských odpadov na vybraných Sb ložiskách na Slovensku . Banské odpady reprezentované predovšetkým odakaliskovými kalmi, haldami a kontaminovanými pôdami obsahujú až 15 700 ppm Sb , 6 800 ppm As a 14,14 hm . % Fe . U väčšiny sledovaných lokalít, hodnoty pH hlušiny a pôdy sú blízkoneutrálne pretože kyslosť produkovaná v dôsledku rozkladu sulfidov je neutralizovaná prítomnými karbonátmi. Hlavné použité analytické metódy boli elektrónová mikrosonda a rtg. mikro difrakcia ( μXRD ) . Obsah Fe a Sb v zrnách tripuhyitu je veľmi variabilná , Fe sa pohybuje v rozmedzí 4,13 - 41,52 hm. % a Sb od 15,94 do 50,83 hm. % .Pomer Fe/( Fe + Zb ) (at./at.%) sa pohybuje od 0,24 do 0,85 s priemernou hodnotou 0,57. Zrná tripuhyitu s pomerom Fe/( Fe + Zb ) blízko do 0,5 sú pomerne dobre kryštalické . Naopak , zrná s vyšším alebo naopak nižším pomerom sú väčšinou slabo kryštalické. In this contribution, we focus on the oxidation of the primary sulphide minerals as the main reason for the crystallization of tripuhyite in the environment of mine wastes at the selected Sb deposits in Slovakia. Mine wastes represented mainly by tailing impoundments, dumps, and contaminated soils contain up to 15 700 ppm of Sb, 6 800 ppm of As, and 14.14 wt. % of Fe. At most of the studied localities, pH values of the tailings and soils are circumneutral because the acidity produced by sulphide decomposition is neutralized by abundant carbonates. The main analytical methods used were electron microprobe and micro X-ray diffraction (µXRD). Content of Fe and Sb in tripuhyite grains is highly variable, Fe ranges from 4.13 to 41.52 wt.% and Sb from 15.94 to 50.83 wt.%. The Fe/(Fe+Sb) (at./at.%) ratio varies from 0.24 to 0.85 with an average value of 0.57. The tripuhyite grains with Fe/(Fe+Sb) ratio close to 0.5 are relatively well crystalline. On the contrary, those with much higher or lower ratio are mostly poorly crystalline. (en)
